Title: Bus stack fault processing system
Inventor: KUNIYOSHI SHUICHI
IPC: H04L69/40
Filed: 1990-03-15
Abstract: PURPOSE:To realize restoration of fault when a processor having a fault stacking a bus is not found out by detecting a cause to a fault in each processor even when bus stack takes place and separating the processor having the fault from the bus. CONSTITUTION:Each node 11 connected to a bus applies health check by a health checking means 14 at a same period periodically respectively. When the health check is unsuccessful, a loopback checking means 13 is driven and a bus separating means 12 is separated for a prescribed time T by a timing generating means 15 and connected again and the operation by the loopback checking means 13 is also restarted. When a processor causing bus stack is separated from the bus, a loopback check in other node is successful for the period only and the loopback check in the processor causing the bus stack is always unsuccessful. The processor of the bus stack drives the bus separating means 12 to separate the bus and to keep the state. Thus, the fault recovery when a processor having the bus stack is not found out is realized.

IPC: G06F17/27
Filed: 1994-04-01
Abstract: PURPOSE:To prevent a user from coming to a dead end during input operation by preventing warning the user that a memory for conversion candidate generation is used too much and to continue fast conversion. CONSTITUTION:A reading inputted from an input part 101 has its morpheme analyzed by a dictionary retrieval part 102 and a morpheme tree generation part 103 sequentially and alternately. In this operation, a memory capacity detection part 107 sends an indication to a display control part 105 to display the possibility of excessive use of the memory at a display part 106 once detecting the usable memory capacity of the morpheme tree generation part 103 becoming less than a certain value, prompts the user to indicate conversion at proper timing, thereby obtaining a Japanese syllabary-Chinese character conversion result at a high speed before a prereading process is interrupted.

Title: Waveform shaping circuit
Inventor: NISHIMAKI MINEO
IPC: H03K12/00
Filed: 1985-03-28
Abstract: PURPOSE:To obtain a rectangular wave with a stable binary logical value by adding an integration circuit with a sinusoidal wave output voltage outputted from a differential amplifier circuit to a comparison reference DC voltage, delaying the phase by 90 deg., and comparing and referencing the signal being the compression of the sinusoidal wave voltage and the sinusoidal wave voltage outputted from the differential amplifier circuit. CONSTITUTION:A signal inputted to an input terminal 16 of a comparison circuit is expressed as f(t)=a sin wt, a signal inputted to a terminal 17 is expressed as g(t)=b cos wt, where (a) is the amplitude of an original signal and (b) is the amplitude after integration processing, and (k) is an amplification factor and they have relation of a=Kb. When the relation of Kb sin wt=b cos wt exists, the relation of tan wt=1/K and DELTAt=(1/w) tan<-1>(1/K) exists, where DELTAt is phase fluctuation and is independent of (a). That is, even when an amplitude fluctuation exists in the output of a frequency generator 11, the output has no effect. Since a comparison circuit 14 and a buffer amplifier circuit 20 are connected in terms of DC, even when the operating bias point of the differential amplifier circuit 12 is fluctuated, no effect is given on the output.

Here, the frame length when the audio signal of the representative sound is divided into the frequency bands is varied by a sampling frequency conversion part 4 to match the period of the waveform of a fundamental frequency component included in the audio signal with the frame length. Then a waveform of one or several cycles of the waveform of the fundamental frequency component included in the audio signal Ai is stored in the memory 5.

Abstract: PURPOSE:To economically measure ice forming speed regardless of the dimensions, shape or distribution of ice in the cross-section of a pipe by determining the product of flow rate of supply water and the content of ice in a slurry calculated from the ratio of electric conductivity between the supply water and the liquid phase part of ice/water slurry. CONSTITUTION:Electric conductivities of supply water to a vacuum ice manufacturing chamber 1 and at the liquid phase part in an ice/water slurry discharged from the chamber 1 are measured simultaneously by means of electric conductivity meters 18, 19 inserted into a water supply pipe 7 and a slurry discharge pipe 5. An operating unit 21 determines the ratio of the electric conductivities and substitutes the ratio into a predetermined equation of the freezing rate and the electric conductivity ratio at liquid phase part thus determining the content of ice in the slurry. The product of the content of ice in the slurry and a flow rate of supply water in the supply water pipe 7 measured by a flow rate meter is then calculated thus determining the ice forming rate (e.g. Ton/Hr) of an ice manufacturing plant.

Title: Solid with grafted surface and its production
Inventor: TSUJII TAKANOBU
IPC: C08F2/36
Filed: 1998-03-16
Abstract: PROBLEM TO BE SOLVED: To obtain a grafted-surface solid highly and uniformly controlled in the primary structure (molecular weight, molecular weight distribution, manner of monomer sequence, etc.), of a graft chain and a surface graft density in the necessary region of a solid surface by grafting a polymer chain onto the surface of a solid through monomolecularly built-up polymerization initiator. SOLUTION: The surface of a solid is not limited on its kind and may be, for example, an inorganic matter such as an oxide, a simple atomic matter such as Si, or a metal. The monomolecular buildup is performed by the Langmuir-Blodgett method. Therefore, polymerization initiating groups are introduced into the surface of a solid by using a polymerization initiator compound of a structure having a hydrophobic group and a hydrophilic group. Generally, a structure represented by the formula: R<1> -A-B-R<2> (wherein R<1> is a hydrophilic group hydrolyzable into hydroxyl or the like; R<2> is a polymerization initiating active group; and A and B are each an organic group). The hydrophilic group is exemplified by an alkoxysilyl. The monomolecularly built-up polymerization initiation groups can be inactivated with an actinic radiation.
